What are you referring to? iPad? iPhone? Macbook? Either way, it (white USB cord and charger) should've come with your item in the packaging. Hope that helps :-/
How would u charge it without a power cord, regardless of device. unless i'r talking about the cord to extend the power adapter of a Mac, and in that case, its to distance.
C'mon folks. We are not mind readers, and therefore, we cannot know where "your" power cord is. Heck, we don't even know what device your power cord is for. In the future, please provide enough information so that we may properly assist you. Thanks.
